Background Capture Issue

[mlch911]

I'm working on a replica of UITabBar. I'm using a LiquidGlassView(.regular) as the background and a LiquidLensView() as the indicator.
When using captureBackdrop(), everything works fine.
When using captureRootView(), the background become clear.
How can I fix this?
